MATTHEW IV." JORY, OF HOBART, INDIANA.

WAGON-AXLE TRUSS.

SPECIFICATION forming part of Letters Patent No. 243,915, dated July 5,1881.

Application filed April 18, 1881. (Nomodel) To all whom it may concernBe it known that I, M. W. J ORY, of Hobart, county of Lake, and State ofIndiana, have invented certain new and useful Improvements in aWagon-Axle Truss andIdo hereby declare the following to be a full,clear, andexact description thereof, that will enable others to make anduse the same, reference being bad to the accompanying drawings, and toletters of reference marked thereon, forming a part of thisspecification.

The object of this invention is an improvement in wagon-axles, wherebythey can be conveniently adjusted to give the required gather and swingto the tapering spindle and impart the required gather to the wheel, theexact construction and arrangement of which will be hereinafter morefully set forth and described in detail.

Figure 1 is an elevation of a wagon axle and bolster embodying myimprovement, and Fig. 2 is a detached view of the truss-bar.

Referring to the drawings, A represents the axle; B B, thethimble-skeins; O, the bolster, and D the axle-truss bar. The truss-barD is attached to the under side of the axle and extends longitudinallytherewith, the ends fitting into recesses in the under side of the axlebetween the same and the inner ends of the skeins B B, as shown in Fig.1 of the drawings. The ends of the truss-bar are rigidly secured to theaxle by means of the bolts a a, which pass through the apertures a a inthe trussbar, andare tapped into the axle. The rectangular apertures a aare for the reception of the bolts a a which pass down through the Theserectangular slots admit of a lateral movement of the truss-bar as thesame is moved nearer to or farther away from the axle by the adjusting-screw F, which passes through the threaded aperture (0 in thelongitudinal center of the truss-bar. The point of the adjusting-screw Fbears against the metallic plate I), attached to the under side of theaxle. By tightening up on the screw F the center of the axle is bowed orforced upward, which has the effect of throwing out the top of thewheel, and when the adjusting-screw is slacked up the opposite effect isproduced. The truss-bar also has the effect of greatly strengthening theaxle, and confines the weight of the load to the center of the same,thereby allowing a thimble-skein of two and one-half inches in diameterto stand the same strain as a three-inch skein would withoutthetruss-bar, and giving a longer tenon to the spoke in the same sizedhub.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a wagon-axle, the combination, with the truss-bar D, provided withthe apertures a a, for the reception of the tap-bolts c a, of the axle Aand the thimble-skeins B B, substantially as described.

2. In a wagon-axle, the combination, with the truss-bar D, provided withthe rectangular apertures c a and the threaded aperture to, of the adjListing-screw F, the bearing-plate b, and the axle A, constructed andarranged as herein shown and described.
